Abstract

• A music reactive LED cube is constructed by Arduino Microcontroller ATmega328P. The components used in this system are Arduino Uno Board, 512 LEDs, npn-transistors (2N2222), 74HC595 ICs, speaker, some resistors. The LEDs are designed into 8×8×8 cube which contains eight rows and eight columns. The output of the system shows various pattern designs of LEDs and also produces melody sound. The controlled program source code is written in C programming language. The error free source code is uploaded to the A Tmega 328P microcontroller and it controls the operation of the whole system. This system can be used for altar decoration, house and advertisement decoration.
